Hi @BioSfera

What version of BuddyPress and WordPress are you using? Which WordPress theme? And which BuddyPress template pack (if you know)?

[BioSfera]

Hi Paul
Buddypress 3.0.0
WordPress 4.9.6–ro_RO
WP Theme - one community (Link ​https://themeforest.net/item/onecommunity-buddypress-theme/3713046)
Affected website : ​http://elenaiotu.ro
Error: ​http://elenaiotu.ro/grupuri/slatina/forum/

Their support is down these days and I m on my own with this issue looking for help.

Thank you
Nicu

Are you using the new Nouveau template pack, or Legacy ? Or have you not changed the setting on upgrade?

[DJPaul]

This bp_group_new_topic_button() relates to the legacy forums, which we removed support for in 3.0. We have the function in our deprecated/3.0.php file, so it ought to be present.

It might be a load order thing but very hard to debug without access to the theme and other plugins.

Do you have a means of searching in all files in your theme for "bp_group_new_topic_button"?

I ll try to find it using Agent Ransack.
What s next?
Thak you once again for your help

[DJPaul]

Just trying to find where in your theme it is, and when/how it is being used.

hi
I found this function inside theme s files /functions file *add_action( 'bp_group_header_actions', 'bp_group_new_topic_button', 20 );* and removed it. I don t get the error anymore and I hope this won t trigger any new *visible errors.
the owner of the theme I suppose he will fix this on futures upgrades.
Thanks soo much for your help, Paul!
best regards
Nicu

That's useful feedback - thanks. We'll see if we can do anything centrally.

Milestone renamed

What's likely happened here is that this site first installed BuddyPress at version 2.7, or any later version. This means that the deprecated code files aren't being loaded. The function bp_group_new_topic_button() is located in these code files.

Something like this should enable loading of the deprecated code and fix this: ​https://gist.github.com/paulgibbs/b2ba64fa3e408500263422018b51cb41
